Collection of the frequently asked questions, shoutout to Sean Andrew Buchan (Digital Research Analyst at the University of Aberdeen) for answering most of the questions

How do I check my HPC usage?​

$ sreport cluster UserUtilizationByAccount users=r04mr23 start=2000-01-01 format=Accounts%20,Cluster%16,Login,Used
--------------------------------------------------------------------------------
Cluster/User/Account Utilization 2000-01-01T00:00:00 - 2024-06-22T23:59:59 (772412400 secs)
Usage reported in CPU Minutes
--------------------------------------------------------------------------------
             Account          Cluster     Login     Used 
-------------------- ---------------- --------- -------- 
                mmsn  maxwell_cluster   r04mr23   281760

Change the r04mr23 with your Maxwell username, it's in minutes, so you have to divide it by 60.

I set my #SBATCH --time correctly but my job is being stopped mid way?​

The reason might be because you didn't set the partition in the first place and your job being assigned to spot-compute which can only be used for running short job no longer than 36 hours.Add the #SBATCH --partition uoa-compute to run job that is longer than 36 hours

How do I check how much storage have I used? du -sh seems to take forever​

Chek home (/uoa/home/r04mr23) directory usage

$ beegfs-ctl --getquota --cfgFile=/etc/beegfs/beegfs-client-uoa-home.conf --uid r04mr23

Quota information for storage pool Default (ID: 1):

      user/group     ||           size          ||    chunk files    
     name     |  id  ||    used    |    hard    ||  used   |  hard   
--------------|------||------------|------------||---------|---------
       r04mr23|193544||   14.19 GiB|   56.00 GiB||    75776|   200000

Check sharedscratch directory (/uoa/home/r04mr23/sharedscratch) usage

$ beegfs-ctl --getquota --cfgFile=/etc/beegfs/beegfs-client-uoa-scratch.conf --uid r04mr23

      user/group     ||           size          ||    chunk files    
     name     |  id  ||    used    |    hard    ||  used   |  hard   
--------------|------||------------|------------||---------|---------
       r04mr23|193544||    2.52 TiB| 1024.00 GiB||  1002345|  1000000

Again change r04mr23 with your Maxwell username, size used is your usage, size hard is the non-official storage limit, try to keep it below hard as suggested by the Maxwell team. chunk files is the file number limit.

How do I check how long did it take for my slurm job to finish?​

sacct --format=JobID,JobName,State,Elapsed -j <JOB_ID>
